7970 is faster than a 1050TI by a good margin, it was launched in 2011.
Hum, first I didn't say anything about the Radeon HD
7970 (Released Dec 22nd, 2011 so more 2012 in my book)
let alone the Ti revision...
I was only was contrasting what Nvidia has provide since the Fermi days, such a GTX 580 was released Nov 9th, 2010 (so < 8yr's now); although the GTX 1050 Released Oct 25th, 2016. it was just 6 years back at that point.
As it being a fair comparison, I'll leave that to others to chime in about. Some might want more than a 70% reduction in TDP, however that's only a single reference for analysis. Better would be the actual power during gaming (Perf/W), which I'd have to believe is the true/correct data to judge from.
You need to just have a look here; unless you next want to discuss the validity of said relative performance data?
